beaches
here are my personal "winners"
1. natural beauty- Cala Bossa, Cala Comte (both north of the island)
2. pleasant crowd-can not comment on that one. depends what you mean by it.
3. seclusion-- cala tarida- just go a bit to the right along the rocky side-and you will find a little "private" beach, also cala gracioneta.
as for south side of the island most places are very crowded
3. bars- cala comte has pretty good list of coctails and best (strongest) sangria, Ses Salines- Sa Trinxa
